University Research – Is globalisation unravelling? – UoA

Source: University of Auckland (UoA)

Where to for globalisation: cooperation, competition, or collapse? World-leading thinkers are exploring what comes next at the first-ever International Economics Workshop in Auckland.

As political allies shift, supply chains reorganise, and major powers butt heads, the University of Auckland is bringing some of the world’s most influential economic thinkers to New Zealand to examine what comes next.

On 4 December, two events will feature global heavyweights tackling the big questions shaping trade, finance, and geoeconomics, and what it all means for Aotearoa New Zealand.

The inaugural University of Auckland International Economics Workshop will explore the geoeconomics of the new world order, strategic industrial policy, macro-financial spillovers, and the geopolitics of trade, climate, and critical minerals.

Among the speakers is Harvard University’s Professor Pol Antràs, one of the world’s most cited authorities on global supply chains and trade fragmentation, and Professor Stephen Redding, an authority on trade and uncertainty. They're joined by experts including former New Zealand Reserve Bank Governor Dr Alan Bollard and former Chief Economist at the Bank of England, now Chief Economic Adviser at PwC, Andy Haldane.

In the evening, the event Geoeconomic Fragmentation: Challenges and Opportunities, will feature Harvard Business School Professor Laura Alfaro, a globally recognised expert on international investment and former Minister of National Planning in Costa Rica. She’s joined by Haldane, and Business School economics professor and member of the Reserve Bank’s Monetary Policy Committee, Prasanna Gai, for an in-depth conversation about the forces reshaping inclusive growth, financial stability, and cross-border spillovers.

Gai says the two events create a rare opportunity to hear directly from the thought leaders shaping global debates.

“Globalisation is changing in fundamental ways,” he says. “These conversations will help us better anticipate risks, adapt policy, and identify where our comparative advantages will lie.”

In recent research, Professor Antràs shows that multinationals don’t just trade with the countries where they have affiliates — they also trade heavily with nearby markets, because sharing fixed costs across their global plants creates deep interdependencies that can magnify the geopolitical spillovers of trade policy. For New Zealand, a small, trade-dependent nation, this shift poses risks and opportunities.

Higher tariffs, US policy swings, and ongoing fractures in global governance all point to a more challenging environment for exporters.

When it comes to trade, climate and migration, University of Auckland Associate Professor Asha Sundaram says she’s looking forward to discussing how globalisation will interact with the rising influence of emerging markets in the world economic order, and the challenges and opportunities that climate change, the race for critical minerals and growing talent flows across borders will engender.

Workshop co-organiser and University of Auckland economics lecturer Chanelle Duley is chairing a panel discussion on trade policy and macroeconomics. She says firms are now at the centre of the story.

“While outsourcing was commonplace in the early stages of globalisation, firms are increasingly expanding their boundaries to secure reliable access to upstream goods as geopolitical tensions and uncertainty intensify.”

These shifts, says Duley, are creating new cross-jurisdictional interdependencies, with important macroeconomic implications for countries like New Zealand.

Analysis – 73% of Enterprises Suffered AI Security Incidents: Is Your Security Framework AI-Ready?

Source: CyberNews – Analysis by Aras Nazarovas.

Not so long ago, we saw highly visible events, such as mainstream chatbots ChatGPT and Grok conversations ending up on Google results and exposing sensitive prompts, private data, and company strategies, which showed as examples of systemic control failure.

If that is not enough, Vyro AI followed by leaving an Elasticsearch server completely open, which included prompts, tokens, and user agents. This is like leaving a data center's doors wide open for everyone to see.

It is, without a doubt, a C-suite issue. In addition to operational risks such as stolen bearer tokens and session artifacts, supply chain vulnerabilities, and trust damage, it also presents significant legal risks that invoke data protection obligations. It's a clear warning for all CTOs, CISOs, and other executives.

These are not nation-state intrusions, sophisticated attacks, or zero-days. These are simple security mistakes with large consequences. A database was left open for anyone to see, and the pattern is repeating across the industry.

Free AI, Hidden Risks

Vyro AI leak? There is no password protection, authentication requirements, or network restrictions. It just misses the basic security that every developer or system engineer needs to follow.

Traditional security frameworks do not work for most AI systems, with unpredictable data flows, processing, and AI operating across different principles. The attack surface extends beyond traditional boundaries.

For example, prompt injection. Attackers can manipulate AI responses by crafting prompts, leading to unauthorized access to user data. This requires no specialized technical skills, only the ability to craft persuasive language that influences the system's behavior. It requires more thought about security than apparently some can provide.

Since 73% of enterprises faced at least one AI-related security incident in the past year, with an average cost of $4.8 million per breach, there is preparation for warfare, but the door is left wide open. Or, as we see, some are building defenses against AI-powered attacks and discussing cutting-edge threats while leaving databases exposed, and nobody admits they forgot to enable authentication.

Human Error or Technical Incompetence?

I agree that human error is inevitable. Not everything needs to be perfect, but it should not be neglected. Cybercriminals are becoming more sophisticated, but the leak connected to Vyro AI is not that. It proves that a simple mistake, like leaving a database open to everyone, can expose user data to attackers for months.  And it could have been avoided if it had been given more attention.

Some people, myself included, think twice before putting sensitive info into AI tools. The Vyro AI server was left unsecured for several months, and once data goes into someone else's system, we can lose control over where it might end up.

Transparency Is Not Profitable

Most AI services do not tell you how they protect or store your data, who has access to it, or how long they keep it. This becomes dangerous whenever everything gets exposed and users know it.

Communities notice the excuses. When the Tea App incident happened, Reddit users immediately questioned the official narrative. A user asked, “Was it just a poorly configured cloud bucket that allows public users to view and download data, meaning it was negligence and not force?” Others called out the official statements that said, “The information was stored in accordance with law enforcement requirements related to cyber-bullying,” a blatant lie.

Users have seen it before: vague statements and blaming external factors, hoping that the attention will not shift to actual security practices. We have noticed that these “sophisticated attacks” have become a lot less complicated to commit.

Everyone deserves to know how their data is stored and protected. Some things should take precedence over saving money while hoarding personal data. And it is your responsibility to do so.

First Steps Towards Compliance

Yes, you can lecture employees on what data they can input into AI and train them to protect sensitive company information, but this is not sustainable, mostly because people are too lazy to think.

Start by considering implementing role-based training using scenario prompts or pre-approved prompt templates. Block high-risk tools, and provide authorized alternatives with safe defaults. It is your job to minimize the risk, starting from the basics.

However, this process should not be limited to recommendations. It needs to be enforced and supported by tooling. Your job is not only about convenience but also about making the easiest path the most secure path.  

And no, that does not mean you should stop using AI. You should use it more wisely. Before I type anything into a chatbot, I often ask myself, “Would I be okay if this info were leaked tomorrow?”

Handle Your Infrastructure (and People) Better

Can your team and your entire infrastructure handle AI demands? Hoping for the best is not a security strategy. If you are planning to add AI or are already using it, treat it like a Tier‑1 data system.

Start with vendor reassurance: invest in and pay for reputable providers, validate private modes and retention settings, do not allow your data to train the models, review SOC 2/ISO  and all that you can possibly think of, keeping in mind that you have company secrets to keep.

Try to establish technical guardrails by routing AI traffic through CASB/SSE, enabling DLP on prompts and outputs, deploying masking or redaction for PII and secrets, default-minimizing and encrypting logs. Try to build an infrastructure you would be proud of, not something that can crumble at the first issue.

The bottom line is that you should not blindly trust your employees. Set clear rules and use necessary tools. Data deserves protection, and until companies face consequences, everyone will continue to be surprised when another “sophisticated” attack is left to be simple negligence.

Consumer NZ – Are the deals real this Black Friday? Possibly not!

Source: Consumer NZ

Consumer NZ's 12-week price-tracking investigation in the lead up to Black Friday reveals how two retailers could be more naughty than nice when it comes to genuine deals.  

Gemma Rasmussen, head of research and advocacy at Consumer NZ, says her team of investigators are always sceptical of the “fizzed up” deals that appear this time of the year.  

“We’ve been tracking 10 products across Briscoes, Harvey Norman, Farmers and Noel Leeming for 3 months to find out how good the specials around Black Friday really are,” says Rasmussen.

“Based on our price tracking, we think Noel Leeming and Harvey Norman could be bending the rules with their promotional pricing, while Farmers and Briscoes follow a rhythmic 'up and down' price pattern, where if you wait long enough, you’ll get a special. They are all contributing to a chaotic, ‘FOMO’ energy as we sprint towards the hyped-up sales tradition and the start of the Christmas shopping spree.”

Rasmussen is dubious that the sales on Black Friday will blow anyone’s minds when it comes to them offering genuine value.

“Our suspicion is that the retailers will continue to fluctuate prices and dazzle us with colours and promotional language as they have over the last few months. But we’d love to be pleasantly surprised.”

They play the game: Briscoes and Farmers

Rasmussen says Briscoes has really created a name for itself for almost always having a sale. In reality, they’re playing by the ‘specials’ rules, where prices regularly rise and fall.

“With Briscoes, our data shows us that if you wait a week or two, generally you will get a deal. Having prices that shift back and forth feels sneaky, and it can make it hard for those who don’t understand there’s a pattern to know what’s a good deal and what’s not.”

Of the 10 items Consumer tracked, 9 were frequently on special at Briscoes, with most falling into a pattern of being on special for one or two weeks and then the normal price for a week or two.

“Our spot-check found Briscoes is playing by the ‘specials’ rules because it does offer shoppers a genuine opportunity to buy at a discounted price, for a limited time, before returning the product to its usual price.”

Consumer found a similar pattern at Farmers, where goods were on special for two weeks, then back to their usual selling price for the following one to two weeks.

“If you've got your eye on something, watch the price across a fortnight, and grab it when it next drops. It’s OK to feel the FOMO, but you don’t need to act on it straight away. Check your finances and what other shops are offering, then, if you still want it, head back – you probably won’t miss out.”

They lure with language: Harvey Norman and Noel Leeming

For 10 of the 12 weeks, most products tracked at Harvey Norman were promoted with deal-saving claims almost every week.

“Harvey Norman stood out in our investigation for the wrong reasons,” says Rasmussen.  

“While the promotional tags changed frequently, the prices only shifted a little.

“Promotions were labelled ‘great price’, ‘super deal’, ‘huge deal’ or a ‘massive stock sell-out’ for 9 of the 10 products we tracked nearly every week we tracked them.

“A toastie maker was priced at $64 for 10 of the 12 weeks we tracked, during which time, it was variously labelled as a ‘great price’, ‘super deal’, ‘massive stock sell-out’, ‘now’ and even a ‘huge deal’.

“When you look at it like that, wouldn’t you reach the conclusion $64 is the normal price, rather than a special?“  

Consumer thinks Harvey Norman could be at risk of misleading customers with all this hype by creating the impression customers are paying less than they usually would.

Consumer’s investigation found Noel Leeming regularly uses the word ‘now’ on its online pricing. “We think the continual ‘now’ pricing creates the impression products are cheaper than their usual price. But the ‘now’ price jumped around from week to week, too.  

“For example, the NutriBullet appeared to be 'now’ on special for 10 out of the 12 weeks, and yet the special price varied between $69 and $91,” says Rasmussen.

“You'd be forgiven for thinking the continual ‘now’ promo means you’d be paying less than you usually would. But that’s not necessarily true.”

They capture our attention – so do this instead

Rasmussen says the pull of a special is always stronger when cost pressures are hitting hard.

“Even though most of us know that Black Friday and Cyber Monday sales are mostly just a big hit of dopamine, you'd be hard-pressed to find a New Zealander who’s immune to the allure of a red strike-through or a percentage discount.

“Use sites like PriceSpy and PriceMe to track sales and learn when pricing is genuinely low. Don't get sucked into the hype. Chances are, there will be another sale in a fortnight,” says Rasmussen.

“Our research shows time and time again that the prices around Black Friday are a bit like shaking up a bottle of Coca-Cola – it’s all fizzy and bubbly and exciting, but when you take a sip, it’s flat, and you realise you’d probably have been fine without it.  

“If an advertisement or promotion raises your eyebrows, send it our way. We’re not afraid to call out this year’s naughty retailers.”

Fonterra updates 2025/26 season Farmgate Milk Price and collections

Source: Fonterra
 
Fonterra Co-operative Group Ltd has today provided an update on its forecast Farmgate Milk Price and milk collections for the 2025/26 season.  
 
The Co-op has narrowed the forecast Farmgate Milk Price range from $9.00-$11.00 per kgMS to $9.00-$10.00 per kgMS, with the midpoint changing from $10.00 per kgMS to $9.50 per kgMS.  
 
The Co-op has also increased its forecast milk collections for the 2025/26 season from 1,525 million kgMS to 1,545 million kgMS.  
 
CEO Miles Hurrell says we’ve seen strong milk flows this season, both here in New Zealand and other milk producing nations.  
 
“This increase in milk supply has put downward pressure on global commodity prices, with seven consecutive price drops in recent Global Dairy Trade events. As a result, we have narrowed the forecast Farmgate Milk Price range for the season and adjusted our midpoint.  
 
“Fonterra started the season with a wide forecast range of $8.00-$11.00 per kgMS. The new midpoint of $9.50 per kgMS is in the middle of this range and remains a strong forecast for the season.    
 
“We continue to be focused on maximising returns for farmer shareholders through both the Farmgate Milk Price and earnings. This includes through building strong relationships with customers who value our products, utilising price risk management tools, and optimising our product mix,” says Mr Hurrell.
 
About Fonterra    
Fonterra is a co-operative owned and supplied by thousands of farming families across Aotearoa New Zealand. Through the spirit of co-operation and a can-do attitude, Fonterra’s farmers and employees share the goodness of our milk through innovative consumer, foodservice and ingredients brands. Sustainability is at the heart of everything we do, and we’re committed to leaving things in a better way than we found them. We are passionate about supporting our communities by Doing Good Together.  

Greenpeace – Ashburton town supply water sample nears national health limit for nitrate; almost double levels associated with reproductive risk

Source: Greenpeace

Greenpeace is deeply concerned about the future of Ashburton’s town water supply, as testing on Sunday revealed that a sample had reached nitrate contamination levels of 9.65mg/L.
“This sample from Ashburton’s town water supply is dangerously close to the New Zealand Government’s limit for nitrate contamination in drinking water,” says Greenpeace freshwater campaigner Will Appelbe.
However, Appelbe notes that this limit is outdated and that there are calls from public health scientists to lower it, in line with findings from a growing body of international research.
“Long-term exposure to nitrate in drinking water at levels much lower than the current health limit – and much lower than this sample from the Ashburton town supply – has been associated with significant health impacts, particularly for pregnant people.”
A 2021 Californian study found that nitrate levels above 5 mg/L is associated with a 47% increased risk of preterm birth. Above 10mg/L of nitrate, the risk increased by 250%. The New Zealand College of Midwives recommends that pregnant people consider an alternative source of drinking water if their supply is over 5 mg/L.
“Ashburton District Council and Environment Canterbury must make the community aware of the risk and provide an alternative safe source of water,” says Appelbe. “Because right now, pregnant people in Ashburton could be drinking this water with no knowledge of the potential risks to them and their baby.”
Greenpeace held water testing events over the last week in Gore, Waimate, and Darfield. It tested approximately 200 water samples over the three events, more than 100 of which were in Darfield.
Environment Canterbury’s Annual Ground Water Quality Survey released in August shows that nitrate-nitrogen contamination is worsening across 62% of groundwater wells, while 18% show no change in contamination and 20% show a decrease, in sites where a ten-year trend can be established.
“Even if we were to stop nitrate pollution immediately, Ashburton’s water would likely still get worse before it gets better. That’s why it’s so important to act now to stop pollution at the source. But right now, Environment Canterbury isn’t even trying to do that,” says Appelbe.
“Since the start of this year, Environment Canterbury has approved – or is in the process of approving – more dairy expansions that will add another 35,000 dairy cattle to the Canterbury plains. More cows mean more nitrate pollution, and more rural communities with undrinkable water.”
“Environment Canterbury must immediately stop dairy expansions, and phase out the use of synthetic nitrogen fertiliser to protect rural communities’ drinking water here in Canterbury. They declared a nitrate emergency in September, and it’s time they put their money where their mouth is.”
